If you query old data present in s3, clickhouse will automatically fetch it as required.

@nitya-signoz any link or docs available for the same.

So apart from adding the retention setting in signoz you don’t need to do anything. But if you want to learn more about tiered storages of clickhouse here are some links. https://altinity.com/blog/2019/11/29/amplifying-clickhouse-capacity-with-multi-volume-storage-part-2 https://github.com/ClickHouse/ClickHouse/issues/3605

@nitya-signoz i have set-up the below retention policy on signoz, but when i search data for last one week i get msg saying like no data to display, also in s3 bucket i can see data and files of tday;s date only. Is my retention policy is properly set.

Total retention period is the time for which data will be persisted either in s3/disk. After which it will be deleted. If you want to search for last week data, you will have to change the value of total retention period to 1 week.
